Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, and in particular to a novel water level monitoring instrument. Background Technology

[0002] A dam is an engineering project used to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. It is also called a water engineering project. In order to facilitate water management and prevent water disasters, it is necessary to monitor the water level at the dam in real time.

[0003] The published patent document with publication number CN218628554U discloses a water level monitoring device for a hydropower station dam, including: a limiting cylinder, the limiting cylinder having a lifting cavity inside and an installation cavity located above the lifting cavity, the bottom wall of the installation cavity having a trigger point extending into the lifting cavity.

[0004] However, the above-mentioned existing technology still has shortcomings in use. The tilt angle of the dam fixing block of the above-mentioned existing technology is fixed and cannot be adjusted. Therefore, it can only be installed and used on the slope of the dam with the same tilt. If it is installed and used on the slope of the dam with other tilts, it will cause the entire device to tilt, which will affect the monitoring effect. Utility Model Content

[0032] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] To achieve the above-mentioned technical features, the purpose of this utility model is as follows:

[0034] See appendix Figure 1-7 A novel water level monitoring instrument includes a water level monitoring and alarm unit connected to a telescopic arm 1. The telescopic arm 1 is connected to a dam fixing plate 3 via an angle adjustment mechanism 2. The angle adjustment mechanism 2 is used to adjust the angle between the dam fixing plate 3 and the telescopic arm 1. The water level monitoring and alarm unit includes an installation cylinder 4 fixedly connected to the telescopic arm. A float 5 is slidably installed vertically inside the installation cylinder 4. A float ball 6 is installed at the bottom of the float 5. A sensor block 7 is provided at the top of the float 5. A trigger point 8 is installed inside the installation cylinder 4 and above the sensor block 7. The trigger point 8 is connected to an alarm light 9 installed on the installation cylinder 4. When the sensor block 7 contacts the trigger point 8, the controller of the alarm light 9 controls the alarm light 9 to sound an alarm. During installation, the distance between the dam fixing plate 3 and the mounting cylinder 4 is adjusted by adjusting the length of the telescopic arm 1. The angle between the dam fixing plate 2 and the telescopic arm 1 is adjusted by adjusting the angle adjustment mechanism 2, making the dam fixing plate 2 suitable for fixed installation on dams with different inclinations. During operation, the float 6 faces the water surface and the float rod 5 is in a vertical state. When the water level rises to the float 6, buoyancy will be generated on the float 6, and the float 6 will drive the float rod 5 to slide along the mounting cylinder 4. When the water level rises to a certain height, the sensing block 7 at the top of the float rod 5 will contact the contact point 8, thereby causing the controller of the alarm light 9 to control the alarm light 9 to sound an alarm, realizing real-time monitoring of the dam water level.

[0035] In one embodiment, the angle adjustment mechanism includes a connector 2a, one end of which is connected to the dam fixing plate 3, and the other end of which is connected to a fixed shaft 2b. The telescopic arm 1 is hinged to the connector 2a via the fixed shaft 2b. The fixed shaft 2b includes a shaft body 2b1 fixedly connected to the connecting plate. The shaft body 2b1 is provided with an indexing plate 2b2, and the circumference of the indexing plate 2b2 is provided with multiple radial holes 2b3. The telescopic arm 1 is equipped with a first fastening bolt 2c for engaging with the radial holes 2b3. During installation, the angle between the dam fixing plate 3 and the telescopic arm 1 can be set by engaging the first fastening bolt 2c with different radial holes 2b3 on the indexing plate 2b2.

[0036] In one embodiment, the telescopic arm 1 includes a first connecting arm 1a with one end hinged to the connecting plate 2a via the fixed shaft 2b. A second connecting arm 1b is fitted inside the first connecting arm 1a. The second connecting arm 1b has a plurality of limiting holes 1c distributed along the length direction. The first connecting arm 1a has a second fastening bolt 1d that cooperates with the limiting holes 1c. The second connecting arm 1b is connected to the mounting cylinder 4. The first fastening bolt 2c is installed on the side of the first connecting arm 1a away from the second fastening bolt 1d. The length of the telescopic arm 1 can be adjusted by the second fastening bolt 1d cooperating with different limiting holes 1c.

[0037] Furthermore, the bottom of the mounting cylinder 4 is provided with a positioning sleeve 10 that is slidably connected to the float 5, and a filter screen cylinder 11 is installed at the bottom of the mounting cylinder 4. The float 6 is slidably connected inside the filter screen cylinder 11. By setting the filter screen cylinder 11, on the one hand, it prevents garbage or debris from entering the gap between the mounting cylinder 4, the positioning sleeve 10 and the float 5, thus affecting the up and down sliding of the float; on the other hand, it can effectively prevent garbage on the water surface from touching or interfering with the float or the float.

[0038] Furthermore, a guide post 12 is installed vertically on the top of the positioning sleeve 10, and a guide block 13 that slides with the guide post 12 is installed on the float 5 near the trigger point 8. Through the arrangement of the guide post 12 and the guide block 13, the float 5 is in a state of two-point support and guidance, one high and one low, that is, the positioning sleeve guides and the guide block guides simultaneously; and the guide support of the guide block is always at the top of the float, making the guidance more effective and stable.

[0039] Furthermore, a first ball bearing guide sleeve 14 is installed between the positioning sleeve 11 and the float 5, so that the float and the steel ball in the first ball bearing guide sleeve form rolling friction, making the frictional resistance of the float moving along the positioning sleeve smaller and smoother, and avoiding jamming.

[0040] Furthermore, a second ball bearing guide sleeve 15 is provided between the guide block 13 and the guide post 12, so that the guide post and the steel ball in the second ball bearing guide sleeve form rolling friction, making the frictional resistance of the guide block moving along the guide post smaller and smoother, and avoiding jamming.

[0041] Furthermore, the alarm light 9 is installed on the top of the mounting cylinder 4, and a rain cover 16 is installed on the top of the alarm light 9.

[0042] Furthermore, a solar panel 17 is installed on the top of the rain cover 16. The solar panel 17 is connected to a storage battery, which powers the alarm light, thereby solving the power supply problem and making this application more widely applicable.

[0043] It should be noted that the trigger point 8 can be a limit switch set above the sensing block 7. When the float 6 rises to the point where it comes into contact with the sensing block 7 and the trigger point 8, the controller of the alarm light 9 receives the signal and controls the alarm light 9 to sound an alarm.
